Could help develop treatments to prevent metastasis (awesome animated video)

June 23, 2016

Metastasis (spread of cancer) is one of the biggest challenges in cancer treatment. It is often not the original tumor that kills, but secondary growths. But a key question in cancer research has been how vulnerable cancer cells are able to survive once they break away from a tumor to spread around the body.

“Metastasis is currently incurable and remains one of the key targets of cancer research,” said… read more

New processor can plan an optimal, energy-efficient robot motion path up to 10,000 times faster

June 21, 2016

Duke University researchers have designed a new computer processor that’s optimized for robot motion planning (for example, for quickly picking up and accurately moving an object in a cluttered environment while evading obstacles). The new processor can plan an optimal motion path up to 10,000 times faster than existing systems while using a small fraction of the required power.

Graphene can be transformed in the lab from a semimetal into a semiconductor if it is confined into nanoribbons narrower than 10 nm (with controlled orientation and edges), but scaling it up for commercial use has not been possible. Until now.

University of Wisconsin-Madison scientists have discovered how to synthesize narrow, long “one-dimensional” (1-D) nanoribbons (sub-10 nanometers wide) directly on a conventional germanium semiconductor wafer.

Australian researchers have discovered that an existing medication could have promise in preventing breast cancer in women carrying a faulty BRCA1 gene, who are at high risk of developing aggressive breast cancer.

Currently, many women with this mutation choose surgical removal of breast tissue and ovaries to reduce their chance of developing breast and ovarian cancer. Notably, in May 2013,… read more

The vehicle, dubbed “Olli,” can carry up to 12 people. It uses IBM Watson and other systems to improve the passenger experience and allow natural interaction with the vehicle. Olli will be used on public roads locally in Washington DC and later… read more

Researchers in MIT’s Media Lab have bypassed a major design step in 3-D printing — quickly and efficiently modeling and printing thousands of hair-like structures.

Instead of using conventional computer-aided design (CAD) software to draw thousands of individual hairs on a computer — a step that would take hours to compute — the team built a new software platform called “Cilllia” that lets users simply define the… read more

Chinese supercomputers maintained their No. 1 ranking on the 47th edition of the TOP500 list of the world’s top supercomputers, announced today (June 20). The new Sunway TaihuLight supercomputer operates at 93 petaflop/s (quadrillions of calculations per second) Rmax on the LINPACK benchmark — twice as fast and three times as efficient as China’s Tianhe-2 (at 33.86 petaflop/s), now in the #2 spot.… read more

Scientists in South Korea have designed ultra-thin photovoltaics that are flexible enough to wrap around a thin glass rod. The new solar cells could power wearable electronics like smart watches and fitness trackers.

“Our photovoltaic is about 1 micrometer thick” (the thinnest human hair is about 17 micrometers), said Jongho Lee, an engineer at the Gwangju Institute of Science and Technology in South Korea. Standard photovoltaics are usually hundreds… read more

AI drug-discovery engine to be presented at Machine Intelligence Summit in Berlin on June 29-30

June 17, 2016

Scientists at Insilico Medicine have developed a new drug-discovery engine that they say is capable of predicting therapeutic use, toxicity, and adverse effects of thousands of molecules, and they plan to reveal it at the Re-Work Machine Intelligence Summit in Berlin, June 29–30.

Drug discovery takes decades, with high failure rates. Among the reasons: irreproducible experiments with poor choice of animal models and inability to… read more

Columbia Engineering researchers announced earlier this week that they have developed a simple way to reduce VR motion sickness that can be applied to existing consumer VR devices, such as Oculus Rift, HTC Vive, Sony PlayStation VR, Gear VR, and Google Cardboard devices.

The trick is to subtly change the field of view (FOV), or how much of an image you can see, during visually perceived motion.… read more

UT Dallas researchers have designed an affordable “electronic nose” radio-frequency front end for a rotational spectrometer — used for detecting chemical molecules in human breath for health diagnosis.

Current breath-analysis devices are bulky and too costly for commercial use, said Kenneth O, PhD, a principal investigator of the effort and director of Texas Analog Center of Excellence (TxACE). Instead, the researchers used CMOS integrated circuits… read more

Harvard scientists have created a system a system that uses solar energy plus hydrogen-eating bacteria to produce liquid fuels with 10 percent efficiency, compared to the 1 percent seen in the fastest-growing plants.

The system, co-created by Daniel Nocera, the Patterson Rockwood Professor of Energy at Harvard University, and Pamela Silver, the Elliott T. and Onie H. Adams Professor of Biochemistry and Systems Biology at Harvard… read more

An FDA-approved exploratory clinical trial of a prototype wearable artificial kidney (WAK) — a miniaturized, wearable hemodialysis machine — at the University of Washington Medical Center in Seattle has been completed, the researchers reported June 2 in an open-access paper in JCI Insight.

The seven patients enrolled in the study reported “significantly greater treatment satisfaction during the WAK treatment period compared with ratings of care during periods of conventional… read more
